Abstract

A wide band directional coupler for microstrip lines has a microstrip line section whose conductive core is coupled to the core of the main line over a length lambda /4 ( lambda being the wave length in a mid portion of the desired pass band). The section has a first fraction parallel to the main line and at a small distance therefrom so as to provide tight coupling and a second fraction diverging from the main line and closed on a matching impedance. The free end of the first fraction is connected to the load and has an extension projecting over a length less than lambda /16 for forming a microcapacitor tapping energy from the main line.
